To all whom it may concern.:

Beitknown that l, HENRI DELMAs-AZMA, of St. Quentin, in the Republic of France, have invented certain new and useful Improvements in Gas-Burners. (for which I have received Letters Patent in France, dated October 8, 1888, No. 157,899, and May 30,1885, No. 169,262; in Germany, dated May 6, 1881, No. 82,681; in Belgium, dated April 26, 1881, No. 64,967; in England, dated May 3, 1884, No. 7,188; in Italy, dated November 80, 1884, No. 17,484; in Austria-Hungary, dated March 1, 1885, No. 89,131 and No. 10,754, and in Spain, dated March 6, 1885, No. l,681,) of which the following is a specification.

rlhe object of myinvention is to effect cornplete and economic combustion of any gas by burning it in a butterfly burner, with heated air iiowing down on the flame from above and under very low pressure.

Figure l is a section of a burner of my system along the line a b; Fig. 2, a section along c d, and Fig. 8 a section along ef.

A is a gasburner of the usual construction,

- the soapstone cap of which has a slit at its top.

B is an oblong glass globe exactly fitted with its socket, and by means of plaster tothe foot of -the burner A. The tlat iame of the butterfly burner has the direction of the greater axis of the globe B. One of the two larger sides of this globe is platinized or silverplated so as to serve as a lateral reflector, if desired.

C is a cover fixed to the upper part of the globe B. It has an oblong shape corresponding to that of the globe B. This cover, made ot' thin sheet metal, serves to heatthe incoming air, and to distribute and Iblow it against the flame. At the same time it serves as chimney to convey the gases of combustion to the outside. rlhe combustion is carried on at very low pressure. A screen or reector, D, is attached to the lower part of the cover C.

E is the central chimney, where the gases are formed, and from which they escape through the mouth F after imparting some oftheir heat to the metallic walls.

G H. are respectively the outlet and inlet casing,of an oblong shape, concentric with the globe B,forniing, in combination with the in termediate casing, I, two chambers or compartments. One ol' the compartments,K, being free and open allows the fresh outside air to rise to the chamber M. The other, L, is furnished with the corrugated metal sheet N, pressing against the wall I and dividing the compartment into a series of alternating chaunels, il i' i i. The air, already somewhat heated, is in a regular manner divided and conveyed by these channels to the llame at a very high temperature.

The casing H is riveted to the horizontal portion ofthe casing G, and is secured to the corrugated sheet N by means of rivets, as in Fig. 3, or by means ot'indentations, as shown in Fig. 1, and as the casing I is secured to the sheet N in a similar manner it will be seen that the cap,comprising the connected casings G H I, is removable bodily from the globe B. Vhen in position, the globe lits within the lower end of casing I, the corrugated sheet N resting at its lower edge upon the upper edge ofthe globe, as shown in Figs. 1 and 2. At its lower edge the casing G is lprovided with a lateral rim or flange, which is adapted to support the reliector D, the latter slipping freely over the cover. By this construction the cover,with the reflector, may be removed from the globe, and the reflector also removed from the cover when desired.

As the whole cover C is of thin sheet metal, and the air-current, first ascending and then descending, forms a kind of siphon, this air carries along with itasulficient amountof heat, so as not to allow of any local concentration of heat that might injure the globe or change its shape.

The apparatus may be applied to any combustible gas whatever. It may also be adapted to round globes and covers.

I am aware of the patent to Krausse, No. 310,209, and I make no claim to anything` therein shown and described. NVhile the same general principle is the same in both, believe that my burner possesses advantages over that just referred to in that it produces a steadier flame, insures more perfect combustion, and effects a material saving of the gas. Neither do Iwish to be understood as clai1ning,broadly, adetachable reflector or a removable cap; but

What I do claim is- In combination with burner A and elliptical globe B, the three 'vertical casings G H I,con nected with but separated from one another to form the concentric chambers K and L,con nected at their upper ends by a chamber, M, cover C, connecting the casings GH, and pro- 1o vided with a central discharge, F, anda plate,

N,corrugated vertically and placed Within the chamber L.

In testimony whereof I have signed this specification :in the presence of two subscribing Witnesses.
